Registry placement date: Sept. 18, 1998
Location: Tucson, approximately bounded by Ruthrauff Road to the north, Prince Road to the south, Pomona Road to the east and La Cholla Boulevard to the west
Contaminants of concern: Trichloroethene (TCE) and chromium
Action taken: In 2013, the final remedial investigation report was issued and the feasibility study (FS) was initiated. ADEQ has been addressing FS data gaps.
A local water provider has been operating an ADEQ-funded wellhead treatment system as an early response action to remove TCE since early 2007.
Status: In 2016, to address FS data gaps, additional boreholes were installed to aid in delineating the lateral extent of the TCE groundwater plume; wells were installed for a planned soil vapor extraction (SVE) pilot system; and shallow soil gas samples were collected. ADEQ plans to address the remaining data gaps and create a draft FS by the end fiscal year 2017.
